Spring RestTemplete支持Https安全请求

实现步骤

Step1: 自定义ClientHttpRequestFactory

package com.example.demo.https;

import org.springframework.http.client.SimpleClientHttpRequestFactory;

import javax.net.ssl.*;
import java.io.IOException;
import java.net.HttpURLConnection;
import java.net.InetAddress;
import java.net.Socket;
import java.security.cert.X509Certificate;

public class HttpsClientRequestFactory extends SimpleClientHttpRequestFactory {
    @Override
    protected void prepareConnection(HttpURLConnection connection, String httpMethod) {
        try {
            if (!(connection instanceof HttpsURLConnection)) {
                throw new RuntimeException("An instance of HttpsURLConnection is expected");
            }

            HttpsURLConnection httpsConnection = (HttpsURLConnection) connection;

            TrustManager[] trustAllCerts = new TrustManager[]{
                    new X509TrustManager() {
                        public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                            return null;
                        }

                        public void checkClientTrusted(X509Certificate[] certs, String authType) {
                        }

                        public void checkServerTrusted(X509Certificate[] certs, String authType) {
                        }

                    }
            };
            SSLContext sslContext = SSLContext.getInstance("TLS");
            sslContext.init(null, trustAllCerts, new java.security.SecureRandom());
            httpsConnection.setSSLSocketFactory(new MyCustomSSLSocketFactory(sslContext.getSocketFactory()));

            httpsConnection.setHostnameVerifier(new HostnameVerifier() {

                public boolean verify(String s, SSLSession sslSession) {
                    return true;
                }
            });

            super.prepareConnection(httpsConnection, httpMethod);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    /**
     * We need to invoke sslSocket.setEnabledProtocols(new String[] {"SSLv3"});
     * see http://www.oracle.com/technetwork/java/javase/documentation/cve-2014-3566-2342133.html (Java 8 section)
     */
    private static class MyCustomSSLSocketFactory extends SSLSocketFactory {

        private final SSLSocketFactory delegate;

        public MyCustomSSLSocketFactory(SSLSocketFactory delegate) {
            this.delegate = delegate;
        }

        @Override
        public String[] getDefaultCipherSuites() {
            return delegate.getDefaultCipherSuites();
        }

        @Override
        public String[] getSupportedCipherSuites() {
            return delegate.getSupportedCipherSuites();
        }

        @Override
        public Socket createSocket(final Socket socket, final String host, final int port, final boolean autoClose) throws IOException {
            final Socket underlyingSocket = delegate.createSocket(socket, host, port, autoClose);
            return overrideProtocol(underlyingSocket);
        }

        @Override
        public Socket createSocket(final String host, final int port) throws IOException {
            final Socket underlyingSocket = delegate.createSocket(host, port);
            return overrideProtocol(underlyingSocket);
        }

        @Override
        public Socket createSocket(final String host, final int port, final InetAddress localAddress, final int localPort) throws
                IOException {
            final Socket underlyingSocket = delegate.createSocket(host, port, localAddress, localPort);
            return overrideProtocol(underlyingSocket);
        }

        @Override
        public Socket createSocket(final InetAddress host, final int port) throws IOException {
            final Socket underlyingSocket = delegate.createSocket(host, port);
            return overrideProtocol(underlyingSocket);
        }

        @Override
        public Socket createSocket(final InetAddress host, final int port, final InetAddress localAddress, final int localPort) throws
                IOException {
            final Socket underlyingSocket = delegate.createSocket(host, port, localAddress, localPort);
            return overrideProtocol(underlyingSocket);
        }

        private Socket overrideProtocol(final Socket socket) {
            if (!(socket instanceof SSLSocket)) {
                throw new RuntimeException("An instance of SSLSocket is expected");
            }
            ((SSLSocket) socket).setEnabledProtocols(new String[]{"TLSv1"});
            return socket;
        }
    }
}

Step2: 设置RestTemplate的RequestFactory

package com.example.demo.https;

import org.springframework.web.client.RestTemplate;

/**
 * Desc: 参考链接：https://stackoverflow.com/questions/17619871/access-https-rest-service-using-spring-resttemplate
 */
public class RestTempleteConfig {
    private RestTemplate httpRestTemplate;
    private RestTemplate httpsRestTemplate;

    public void init() {
        this.httpsRestTemplate = new RestTemplate(new HttpsClientRequestFactory());
        this.httpRestTemplate = new RestTemplate();
    }
}
